1. "Isn't stainless steel supposed to never rust? Why did my piece get tarnished?"
This is the most common misunderstanding. Stainless steel is not absolutely immune to rust; it is "resistant to corrosion".
Reason: If the environment is humid, near the sea (with high salt content), or comes into contact with strong acidic cleaners, the surface protective film will be damaged.
Solution: Use a dedicated stainless steel cleaner and do not scrub with a steel wool brush; otherwise, it will damage the surface's passivation layer.
2. What are the differences between 304 and 316 stainless steel?
SS 304: The most commonly used grade in residential applications. It has good corrosion resistance and is sufficient for indoor and most urban outdoor environments.
SS 316: Medical/sea level grade. It contains molybdenum and has extremely strong anti-corrosion properties, suitable for coastal areas or high-chloride environments (such as near swimming pools).
3. How to identify genuine 304 stainless steel?
Chemical test: Use the commercially available "stainless steel testing solution", drop it on an inconspicuous part of the handle, and observe the color change (304 will show green or colorless, while manganese steel will turn red).
Magnetic test: True 304 may have a slight magnetism after processing, but if the magnetism is very strong, it may be 201 stainless steel (which is prone to rust).
4. Which is better, satin finish (Satin) or mirror finish (Polished)?
Satin (SS/SSS): The most popular. It is attractive, does not leave fingerprints or scratches easily, and is suitable for frequently used doors.
Polished (PS/PSS): Like a mirror. It has a high visual quality but is very prone to fingerprints and requires frequent wiping, suitable for minimalist or hotel-style.
5. Are the differences between "solid" (Solid) and "hollow" (Hollow) significant?
Solid: Heavy and sturdy to the touch, with extremely strong impact resistance and a long lifespan, but more expensive.
Hollow: With a tubular internal structure, it is more affordable. As long as the wall thickness is sufficient (usually above 1.0mm - 1.2mm), it is completely sufficient for daily household use, but has a lighter touch.
